The invention discloses a cement clinker burning catalyst. The cement clinker burning catalyst is an aqueous solution composed of zinc acetate, cobalt acetate, nickel acetate, lanthanum acetate and cerium acetate, in which the mass ratio of each substance is zinc acetate: 5-8%, cobalt acetate is 3-5%, nickel acetate is 4-6%, lanthanum acetate is 4-6%, cerium acetate is 5-7%, and the balance is water. Spraying the aqueous solution of the present invention into the cement raw meal at a ratio of one ten thousandth can accelerate the formation of cement clinker minerals and improve the burnability of the raw meal. The composition of the cement clinker burning catalyst of the present invention is mainly organic salts, which will not cause adverse effects on equipment and the environment.
Description
technical field [0001] The invention relates to the field of cement additives, in particular to a cement clinker sintering catalyst without harmful components. Background technique [0002] Portland cement is mainly composed of clinker, and the calcination of clinker is the core link of cement production, which determines the output and quality of cement. During the formation of cement clinker, from the decomposition of calcium carbonate, active free calcium oxide appears in the material, and it combines with silicon dioxide, iron oxide and aluminum oxide in the raw meal through the particle Interdiffusion and solid phase reaction to form clinker minerals. Adding some catalytic additives can reduce clinker sintering temperature, increase production efficiency, improve clinker quality and reduce energy consumption. At present, fluorite is widely used, which is mainly used in shaft kilns, and its addition amount is generally 1%. However, fluorite contains fluorine, which is ...
